All the parts of this reconstructed biobrick come from the iGEM registry.
K1334025 is composed of three main parts. A constitutive lacI repressor generator(J23106,P0412), an inducable promoter which can be activated by adding IPTG(R0011), and an E7 lysis protein which can result in the lysis of E.coli if being expressed. This reconstructed biobrick can be used to prove the function of E7. When IPTG is added to the mixture, the growth rate of E.coli drops. Besides, this part can also be used to help the release of a target protein to the exterior of cell when you add such a protein part(with its independent promoter) to the end of this part.
RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

represillator of Elowitz and Leibler (2000)
Coding region for the LacI protein with an LVA degradation tail and without an RBS. LacI binds to the pLac regulator <bb_part>BBa_R0010</bb_part> and PLlac01 hybrid regulator <bb_part>BBa_R0011</bb_part> and inhibits transcription. IPTG (Isopropylthiogalactoside) binds to LacI and inhibits its operation, therefore promoting transcription. A rapid degredation tail (LVA) has been added to improve the High to Low performance of this part.

[ELOW00] References (unparsed) here: Elowitz, M.B., Leibler, S. A synthetic oscillatory network of transcriptional regulators. Nature 403, 335-338 (2000). [ELOW00] Sequence taken from the repressilator of Elowitz and Leibler (2000). The obtained sequence was compared to the wild-type sequence for LacI obtained through a database search. The sequence had been modified from the wild-type in that wild-type GTG start was changed to an ATG start (note, actual ORF in E.coli has several GTG starts it would seem). The LVA tag has been added for quicker degradation. Incompatible with systems containing LacI, lactose, or IPTG.

Double terminator consisting of BBa_B0010 and BBa_B0012
Lysis gene (promotes lysis in colicin-producing bacteria strain)
This lysis gene encodes for the lysis protein in colicin-producing strains of bacteria. Once activated, it causes the host cell to lyze. It also removes the immunity protein out of colicin, and hence, activates the endonuclease activity of the colicin.
IPTG activated promoter similar to R0011
7 nonsense base pair(tactaga) is added to the end of R0011 by PCR.
7 nonsense base pair(tactaga) is added to the end of R0011 to form this part.
7 nonsense base pair(tactaga) is added to the end of R0011 to make it easier to PCR another biobrick.
Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.
